IMPROVEMENT IN SPARK-CONVEVERS.

Specitication forming part of Letters Patent No. 187,001, dated February 6, 1877; application tile@ November 27, 1876.

l plied. Fig., 2 is a top-plan view ot the smokestackand part of one ot' the conveyer-tubes.

'Fig. 3 is a top-plan view of the coupling-tube andits connections. Fig. 4 is a top-plan view ot'.

the rear end of one of the conveyer-tubes.- Fig. 5 is aV vertical sectional view on the liue x x, Fig.4. Figs. 6 and 7 are front views ot' the rests for the couveyer-tube and couplings.

The nature of my invention consists in constructing a locomotive sparkcon veyer, so that the coupling between the conveyer-tubes may move freely in the same, to enable curves to be easily turned and the oscillation ofthe cars when in motion accommodated, and also in providing the conveyer-tube at its rear with 11 funnel-mouths or air-apertures, all as hereinafter more fully described.

The construction and operation of my invention are as follows: Ais the smoke-stack, constructed in the usual manner. B is the conveyer-tube, which passes from the mouth ot' the smoke-stack Aover the engine, and partly over the tender ot' the same. This tube B is held in position at its rear end by means of an upright, b4, -attached to, and extending up from, the tender. To this upright is securely attached, at its upper section, two curved rests, b2 b3, as shown in Fig. `7. In the rest b2 is placed the conveyer-tube B. Each car may be provided with these rests. The front b of this tube B is made flaring, and ext-ends partly l over the mouth of the smoke-stack A, being provided with a sliding cover, a, as shown in Fig. 2, that can be moved back and allow the free exit of smoke, &;c., from the stack when the cars are not in motion. When the cars are in motion, this cover a. extends over the entire mouth of the smoke-stack. 'O is another couveyer-tube, and extends horizontally across the entire top of the car. At its front end c it is' made slightly haring, and at its rear end it is provided with one or more draftopenings, c1 01,-as shown in Figst and 5. Practical experience has shown that locating these draft-openings at the rear of the conveyer-tube ren .ers the same very effective, as they create a vacuum in thatportion ot' the tube which the smoke, sparks, Ste., rush in to lill. To the top of the front and rear of each car is pivoted a rest, c2, of the form shown in Fig. 6, in which part of the couplings are placed when in use. These rests are sut'- liciently large as not to interfere with the free side movement of the coupling-tubes when turning curves. When the caris not in use, these rests are laid tlat down on the top of the car. To the rear section of the tube B is hinged a short tube, D. The end d ot' this tube, which its on the tube B, is enlarged so that the tube B may move4 freely therein in turning curves, and also may accommodate itself to the oscillation ot' the train when in motion. When the cars are not in use this tube D is thrown back, and occupies the curved rest b3. In the flaring mouth c of the conveyer-tube O is inserted a short tube, D1, having also a aring mouth, d. This tube D1 also moves freely in the tube O, to enable curves to be easily turned and also to accommodate itself to the oscillation of -the cars. D2 is the coupling-tube, pivoted at one end by pins d1 to the daring mouth d of the tube D, and having its other end d2 enlarged so as to tit over the tube D. This coupling-tube is secured to the tube D by means of a latch, d3.

The operation is as follows: When the train is being made up, the tu'be D is removed from the rest b3, and its enlarged end d inserted over the end of the conveyer-tube B. The

tube D1 is inserted in the conveyer-tube O, the

rest c2 being raised so as to support the same. The tube D is then inserted in the couplingtube D4, and the latch d3 fastened. Before the train starts, the sliding cover a, is pushed forward so asto cover the mouth of the smoke-A stack, and through the forward motion ot' the train, aided by the suction caused by the draftopenings c1 c1 in the conveyer-tube C, the sparks, cinders. &:c., are carried back and discharged at the rear of the train.

What I claim as new, and desire to secure by Letters Patent of United States, is

1. In combination with the smokestack of a locomotive, a convcyer-tube, having a flaring mouth, b, and provided with a sliding cover, located over the mouth of the smokestack, as and for the purpose specified.

2. In a locomotive spark-conveyer, the combination of the conveyer-tube B, having a flaring mouth b, sliding cover a, hinged tube D, rests b2 b3, and smokestack A, substantially as described.

3. In a locomotive spark-conveyer, the combination of the tube D1, working loosely in the enlarged end of tube C, support c, coupling-tube D2, pin d1, and latch da, substantially as and for thepurposc specied.

4. In a locomotive spark-conveyer. the combination of the smoke-stack A, conveyer-tube B, having sliding cover a, rests bz b3, tubes D D1, coupling-tube D, latch d3, and conveyertube C, having draft-openings c1 c1, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
